Had proac super tablettes back in 80s (target hj24t stands) .....front end roksan xerxes, rega rb300(rewired van den hull), audio technica at-f5.... and the weak link, Arcam delta 90.... So whilst I never respectfully gave them the quality amplification they would have loved... I have a lot of respect for the manufacturer and their products....I could even bi amp with my parasound halo power amp(though have never heard proac/Halo paired)
